LAMP-CHIMNEY.

Specification of Letters Patent.

Patented Feb. 25, 1919.

Application filed February 6, 1918. Serial No. 215,661.

following is a full, clear, and exact descrip- 7 tion.

My invention relates to lamp chimneys and more particularly to the means provided on the chimney at the base for engagement by the spring fingers usually prpvided on the burnerfor retaining the chimney in position.

The object of my invention is to provide an improved means to receive the fingers of the burner and adapted to be engaged by the latter without giving the spring fingers or burner any special shape for the purpose.

Reference is to be had to the accompanying drawings forming a part of this specification in which similar reference characters indicate corresponding parts in both the Views.

Figure 1 is a perspective view of a chimney embodying my invention, showing the same in position on the burner;

Fig. 2 is a horizontal section taken through the chimney in a plane approximately as indicated by the line 2-2, Fig. 1.

In carrying out my invention the lamp chimney 10 will be of any approved shape,

approximately cylindrical at the lower end as usual to seat on a lamp burner A, said burner being of anyapproved form having 7 the usual upwardly extending spring fingers a within which the lamp chimney is received when seating on the burner.

The improved chimney is formed near the lower end thereof with integral lateral closed loops 11, thereby presenting vertical eyes or openings 12 closed at all sides. The

laterally, said loops being loops 11 are positioned and spaced in correspondence with the positions of the spring fingers at of the burner. In placing the chimney on the burner, the fingers a are simply passed upwardly through the respectir e loops 11 and thereby the chimney will be held against any possible displacement by tilting. The loops are of a character to be readily molded on the chimney in the formation of the latter. It will be seen that no unusual formation needs to be given to either the burner or its fingers a.

It will be observed that the engagement of the chimney with the fingers a of the burner is not by reason of shoulders as my improved chimney is free from shoulders at the loops, the inner surface of each loop merging into the adjacent surface of the chimney without shoulders.

Having thus described my invention, I claim as new, and desire to secure by Letters Patenti 1. A lamp chimney formed at the base thereof with integral closed loops projecting spaced to correspond with the positions of the spring fingers on a lamp burner and presenting vertical openings closed "at all sides adapted to receive said spring fingers.

2. A lamp chimney formed at the base thereof with integral closed loops projecting laterally, said loops being spaced to correspond with the positions of the spring fingers on a lamp burner and presenting vertical openings closed at all sides adapted to receive said spring fingers, the inner side of each loop being continuous with the adjacent surface of the chimney to present unshouldered continuous smooth surfaces at the interior of the loops adjacent to the chimney.
